Zebra Label Printer Script

This script converts a PDF file to ZPL (Zebra Programming Language) format and sends it to a Zebra label printer. It includes functionality to:

• Convert PDF to an image
• Resize the image to fit label dimensions
• Convert the image to ZPL format
• Send the ZPL code via Ethernet or serial port
• Save the ZPL code to a file

Requirements

• Python 3.x
• Install required libraries using:

  pip install pdf2image pillow pyserial

• Poppler for Windows (add to PATH or specify poppler_path)

Usage

1. Convert PDF and Save ZPL to File:

   save_zpl_to_file(zpl_command, 'my_label.zpl')

2. Send ZPL to Printer via Ethernet:

   send_zpl_over_ethernet(zpl_command, '192.168.0.1')

3. Send ZPL to Printer via Serial Port:

   send_zpl_over_serial(zpl_command, 'COM3')

Label Dimensions

• Default label width: 10.16 cm (4 inches)
• Default label height: 15.24 cm (6 inches)
• DPI: 300

You can adjust these dimensions by modifying the label_width_cm, label_height_cm, and dpi values in the script.

Notes

• Ensure the printer's IP address and serial port configuration are correct before sending data.
• The script processes only the first page of the PDF.
